This study found that patients with lower socioeconomic status who survived 30 days after initial hospitalization for atrial fibrillation or flutter had higher 1-year all-cause and cardiovascular mortality, received less cardiovascular treatment, and were more likely to be diagnosed with stroke and heart failure.
Aims To examine socioeconomic differences in care and outcomes in a 1-year period beginning 30 days after hospital discharge for first-time atrial fibrillation or flutter (AF) hospitalization. Methods and results This nationwide register-based follow-up cohort study investigated AF 30-day discharge survivors in Denmark during 2005-2014 and examined associations between patient's socioeconomic status (SES) and selected outcomes during a 1-year follow-up period beginning 30 days post-discharge after first-time hospitalization for AF. Patient SES was defined in four groups (lowest, second lowest, second highest, and highest) according to each patient's equivalized income. SES of the included 150 544 patients was: 27.7% lowest (n = 41 648), 28.1% second lowest (n = 42 321), 23.7% second highest (n = 35 656), and 20.5% highest (n = 30 919). Patients of lowest SES were older and more often women. Within 1-year follow-up, patients of lowest SES were less often rehospitalized or seen in outpatient clinics due to AF, or treated with cardioversion or ablation and were slightly more often diagnosed with stroke and heart failure (HF) and significantly more likely to die (16.1% vs. 14.9%, 11.3% and 8.1%). Hazard ratios for all-cause mortality were 0.64 (95% confidence interval 0.61-0.68) for highest vs. lowest SES, adjusted for CHA(2)DS(2)-VASc score, chronic obstructive pulmonary disease, rate- and rhythm-controlling drugs, and cohabitation status. Conclusion In 30-day survivors of first-time hospitalization due to AF, lowest SES is associated with increased 1-year all-cause and cardiovascular mortality and fewer cardioversions, ablations, readmissions, and outpatient contacts due to AF. Our findings indicate a need for socially differentiated rehabilitation following hospital discharge for first-time AF.
